Hi,
I am using the NRF8001 in UART mode and attempting to bond with my android device (Lollipop 5.0 Nexus 6).
i am using the nordic arduino sdk which is found here:...
Hi, I'm using the nRF8001 in an application that requires security so bonds to the remote client/central. My device supports firmware upgrades that may involve new nRF8001...
Hello.
Initially when reading the Gazell documentation I didn't think it'd be a problem but now in Keil seeing this has introduced some doubt whether it's a thing:

Hello all,
I'm building a project on the nRF52382 with the S132 (v2.0.0-4.alpha). The project includes a Central device (GATT Clients) that read and write to 2 peripheral...
Are there any specs available regarding the performance of the nRF52 ADC's internal voltage reference? Accuracy (%) and temperature drift (ppm/degC) would be good. I couldn...
Hello,
I'm developing proprietary radio protocol using nRF52 (not using softdevice) and would like to know if it is allowed to write NRF_RADIO->FREQUENCY register while...
Hello, I've got a problem with an app_timer
